Little Ringed Plover (Charadrius dubius) Science Article 2 abstract At a site in eastern England, wire mesh cages were placed over little ringed plover Charadrius dubiusnests to protect their eggs from predation. The adult birds continued incubating their eggs and no nestdesertions were attributed to cage placement. Protection with cages resulted in an increase inproductivity, […]

Do northern lapwings Vanellus vanellus and little ringed ploversCharadrius dubius rely on egg crypsis during incubation?
Little Ringed Plover (Charadrius dubius) Science Article 1 abstract We studied the possible role of clutch crypsis in antipredator behaviour in tworelated species of ground-nesting waders with camouflaged eggs, the northern lapwing (Vanellusvanellus) and the little ringed plover (Charadrius dubius). We examined whether this behaviourappears regularly in both species and tested the difference in the […]

EASTERN WOOD-PEWEE ATTEMPTS TO FEED KILLDEER CHICKS
Killdeer (Charadrius vociferus) Science Article 2 abstract In July 1988, a wild Eastern Wood-Pewee (Contopus virens) was observed attempting to feed two captive Killdeer (Charadrius vociferus) chicks throughout one day. The Killdeer were in an open air pen close to a forest edge. This was an unusual adoption, involving an altricial species feeding precocial young. […]
Diet of nesting Killdeer in North Dakota
Killdeer (Charadrius vociferus) Science Article 3 abstract Killdeer (Charadrius vociferous) is one of the most widespread of all North American shorebirds and, unlike other shorebirds, tolerates a wide variety of open inland habitats in addition to the shores of coastal and inland water. JEANNE M. FAIR, PATRICIA L. KENNEDY, AND LOWELL C. MCEWEN, Wilson Bull., […]
SPACE USE OF KILLDEER AT A GREAT BASIN BREEDING AREA
Killdeer (Charadrius vociferus) Science Article 6 abstract Wetland conservation efforts require knowledge of space use by a diversity of waterbirds. However,determining space use of animals requires intensive monitoring of individual organisms. Often, activity patternsduring much of the annual cycle are neglected in analyses of home range and habitat use. From 1995
ENERGY EXPENDITURE IN REPRODUCTIVE EFFORT OF MALE AND FEMALE KILLDEER (CHARADRIUS VOCIFERUS)
Killdeer (Charadrius vociferus) Science Article 1 abstract The reproductive investment strategies of the sexes during the breeding season are detailed for Killdeer (Charadrius vociferus), a monogamous plover. I measured the energy investments of the sexes in reproductive, mating, and parental effort. As predicted, males expend more mating effort than females; however, the sexes expend equal […]
Incidental Kill of Dunlin and Killdeer by Strychnine
Killdeer (Charadrius vociferus) Science Article 5 abstract Strychnine poisoning of 36 dunlin (Calidris alpina) and two killdeer (Charadriusvociferus) in Yolo County, California (USA) was documented from 1 1 to 17 December 1990. Birds were found dead on a field containing treated wheat seeds (337 zg strychnine/g seed) in postures consistent with the known physiopathology of […]
Nest fate and vegetation characteristics for Snowy Plover and Killdeer in Colorado, USA
Killdeer (Charadrius vociferus) Science Article 4 abstract We quantified vegetation characteristics at nest sites of Snowy Plovers (Charadrius alexandrinus) and Killdeers (C. vociferus) in south-eastern Colorado during 1995 to assessinterspecific differences in nesting habitat and determine whether habitat characteristics influenced nest fate. Killdeers nested in areas with significantly more grass, litter, and vegetation within 10 […]
Status of Kentish Plover(Charadrius alexandrinus) in Hungary
Kentish Plover (Charadrius alexandrinus) Science Article 7 abstract Population size, distribution and reproductive success of Kentish Plovers in Hungary are sum-marised. 105-140 pairs bred in 1988-1992. Two breeding sites (Miklapuszta and Southern Hun-gary) contained the bulk of the population, with 60-80 pairs and 35-40 pairs, respectively. Thenumber of breeding pairs has declined in recent years.
